Peptides and proteinsChapter 36 :

چکیده
Peptides, proteins, and amino acids are often mislabeled and the terms applied as if they were interchangeable, yet they are different in their characteristics, uses, biological activities, and cosmetic potential. After defining peptides and proteins, the first part of the chapter discusses the specificities of these molecules and their physiologic, biological function, particularly in the skin; what can they do, what are the obstacles to their use in cosmetic products and how these obstacles can be overcome. In the second part, concrete examples of peptides and proteins in dermocosmetics, in particular for the “antiaging” sector, is discussed before concluding with an outlook for the future of this ingredient category in skincare.

Effects of Canola Bioactive Peptides on Performance, Digestive Enzyme Activities, Nutrient Digestibility, Intestinal Morphology and Gut Microflora in Broiler Chickens
The aim of the present study was to evaluate the effects of canola bioactive peptides (CBP) produced by enzymatic hydrolysis of canola meal on performance, digestive enzyme activity, nutrient digestibility, gut microflora and intestinal morphology of broiler chickens. A total of 250 one-day-old Ross 308 male broiler chicks were randomly allocated to 5 dietary treatments with 5 replicates of 10 ...
متن کاملAntimicrobial Peptides Derived from Milk: A Review
Milk proteins provide a natural source of bioactive peptides with potential health benefits and applications in the food industry. The release of these peptides from milk proteins is achieved either by hydrolysis using digestive proteases or by lactic acid bacteria fermentation. Peptides, particularly those derived from milk proteins, can exert a wide range of nutritional, functional and biolog...

Objective(s):This study aims at exploring cytotoxic activity of different peptides derived from VSVG protein against MCF-7 and MDA-MB-231 breast cancer cell lines and human embryonic kidney normal cell (HEK 293). Materials and Methods: The ANTICP web server was used to predict anticancer peptides. The cytotoxic activity of peptides with high score (P26, P7) and low score (P19) was examined b...
متن کاملThe effects of morphine and nicotine co-administration on body weight, food intake and appetite-regulating peptides in rats
Previous studies in humans and animals have reported that nicotine administration decreases body weightand caloric intake. Opiate and cigarette have been used concomitantly as drug abuse. The aim of the present study was, therefore, to analyze the effect of chronic co-administration of nicotine and morphine on food intake, body weight and on some feeding-associated peptides. All experiments wer...
متن کاملIn silico prediction of anticancer peptides by TRAINER tool
Cancer is one of the causes of death in the world. Several treatment methods exist against cancer cells such as radiotherapy and chemotherapy. Since traditional methods have side effects on normal cells and are expensive, identification and developing a new method to cancer therapy is very important. Antimicrobial peptides, present in a wide variety of organisms, such as plants, amphibians and ...
