Introduction
Collagen is the main structural protein of the different
connective tissues, such as skin, bone, cartilage and tendons, and
comprises about one-third of total proteins in mammals. Collagen
extracted from collagen-rich materials with hot water is known
as gelatin. The common materials used for extracting gelatin
include pig skin (46%), bovine hide (29.4%), bones (23.1%)
great attention in recent years due to the religions, cultures and
health concerns. The further enzymatic hydrolysis of gelatin
results in collagen hydrolysate (CH). CH has long been used in
pharmaceuticals and foods in many countries and regions, such
as United States, Europe, China and Japan. Approved as Generally
the Food and Drug Administration (FDA) Center for Food Safety and
Nutrition. The bioavailability and absorption of CH have also been
widely studied. It has been reported that CH is more easily absorbed
and has higher bioavailability than gelatin [2,3]. Besides free amino
acids, small peptides especially dipeptide and tripeptide are also
absorbed into body by peptide transporter 1 (PepT1) [4]. To date,
more than30 peptides (mainly dipeptides and tripeptides) have
the most abundant collagen-derived peptide [5-7]. These peptides
studies reported [8-9]. In this paper, we will mainly focus on the
CH in animal experiments and clinical trials (Figure 1). The possible

Benecial Eects
CH itself has good antioxidant activity as demonstrated by
in vitro assays [10,11]. CH intake also increases the activities of
antioxidant enzymes in body, including SOD, GSH-Px and CAT
[3,12]. Nuclear factor E2-related factor 2 (Nrf2)-antioxidant
response element (ARE) pathway plays a central role in regulating
antioxidant enzymes. Therefore, we speculate that CH exerts it
antioxidant effect in a direct and/or indirect manner. More work is
needed to investigate the effect of CH on Nrf2-AREsignaling.
Anti aging effect of CH has been widely investigated in several
animal models, including photo aged model, chronologically aged
model and acetone-induced dry skin model [3,12-15]. General
the formation of deep wrinkles and improving skin elasticity, are
also observed in clinical trials after taking 10g of CH once a day
for more than 6 weeks [16]. It should be noted that anti aging
effect of CH is more obvious on women aged more than 30 years.
the dual effects of CH on skin collagen synthesis and degradation,
as previous study reported [13].
Anti osteoporotic and anti osteoarthritis effects of CH have been
the symptoms of osteoarthritis and osteoporosis [18]. Combined
CH with other nutritional ingredients has received much interest.
It has been reported that combined oral administration of CH with
calcium and vitamin D has better effects on bone health than alone
administration of CH or calcium and vitamin D [19-21]. Future
studies are needed to determine the optimal form and optimal dose
of CH.
Oral administration of marine CH is reported to enhance
cutaneous wound healing and angiogenesis in rats [22-23]. In
addition to elevated VEGF and FGF-2 expression, the effect of CH
wound healing, as previous study reported that Pro-Hyp, a collagen-
Glycine is one of the major structural units of collagen,
accounting for one-third of the amino acids.CH has the ability
cytokine via glycine-gated chloride channels (GlyR).
Liang et al. reported CH intake inhibited spontaneous tumor
incidence and increase life spanin sprague-dawley (SD) rats
[26]. Our previous study found that CH intake inhibited platelet
release and down regulated proangiogenic factors in blood [27].
Considering angiogenesis is of key importance in the process of
tumorprogression. Our results provide a possible mechanism
underlying antitumor effect of CH.
Antihypertensive effect of CH has been reported in animal
experiments and clinical trials [28,29]. Oral administration of
pressure by inhibiting angiotensin I converting enzyme (ACE)
[28]. Tang et al. [30]found that oral administration of collagen
tripeptide had an inhibitory effect on atherosclerosis development
in hypercholesterol emic rabbits [30]. Platelets are involved in the
patho physiology of atherosclerosis and thrombosis.CH has an
inhibitory activity on platelet release and platelet aggregation, which
may justify potential application of CH as a health care supplement
to prevent and/or treat atherosclerosis and thrombosis-related
cardiovascular diseases [27].
CH intake has an effect on the absorption and metabolism of
weight gain and down regulates serum levels of total cholesterol,
triglyceride and low-density lipoprotein [31]. Further, CH could
alter lipid metabolism-related gene expression and the unfolded
protein response in mouse liver [32]. The hypoglycemic effects
of CH have also been reported [33,34]. It has been reported that
CHcan improve glucose tolerance by inhibiting intestinal glucose
uptake and enhancing insulin secretion [34], suggesting the anti
diabetic property of CH.
Conclusion and Perspective
effects on body health. Those effects make CH new and potential
healthcare supplement for disease prevention and/or treatment
in pharmaceuticals and foods. However, several issues should be
noted and need to be further explored. First, many in vitro studies
only focus on the biological activities of CH, neglecting its tolerance
in gastrointestinal tract. Certain collagen peptides isolated in in
vitro studies may be hydrolyzed by gastrointestinal enzymes and
exert no biological activity in body as expected in in vitro studies.
In vitro simulated GI digestion and Caco-2 mono layers have been
widely used and allow the prediction of oral compounds digestion
effects of CH have been reported, what is the peptide sequence
activity relationship will guide the application of CH. Third, the
biological activities of protein hydrolysates are highly affected by
their molecular structure and weight, which are greatly impacted
by their processing conditions. Therefore, processing conditions
effect.
