Construcción de una biblioteca de plásmidos para la producción de oligopéptidos de variadas secuencias en la levadura ( Saccharomyces cerevisiae)
(Universidad Nacional Agraria La MolinaPE, 2018)
Las bibliotecas de plásmidos son consideradas fuente de diversidad porque agrupan a fragmentos clonados con diferentes secuencias que se pueden emplear en ensayos de tamizaje. Para la presente investigación se construyó ...
Búsqueda de oligopéptidos aleatorios con capacidad fotoprotectora en Saccharomyces cerevisiae
(Universidad Nacional Agraria La MolinaPE, 2020)
Los altos niveles de radiación, el riesgo de contaminación de mares y ríos, y la poca seguridad que otorgan algunos activos presentes en los bloqueadores solares han dado lugar a la búsqueda de nuevos componentes fotoprotectores ...
Physical reasons for the unusual α-helix stabilization afforded by charged or neutral polar residues in alanine-rich peptides
(National Academy of Sciences, 2000-11)
We have carried out conformational energy calculations on alanine-based copolymers with the sequence Ac-AAAAAXAAAA-NH2 in water, where X stands for lysine or glutamine, to identify the underlying source of stability of ...
Impact of different enzymatic hydrolysates of whey protein on the formation of pyrazines in Maillard model systems
(Elsevier, 2019-04)
The generation of pyrazines in model systems containing enzymatically hydrolyzed whey protein under dry heating conditions was studied. Pyrazines are important Maillard flavor compounds. Hydrolysates, obtained with different ...

(Universidade Federal de Minas GeraisUFMG, 2010-03-31)
PREPARATION OF ENZYMATIC HYDROLYSATES WITH HIGH OLIGOPEPTIDE CONTENT AND ANGIOTENSIN-CONVERTING ENZYME INHIBITORY ACTIVITY FROM WHEY PROTEIN CONCENTRATE USING PANCREATIN AND PAPAIN.Protein hydrolysates have been used in ...
Termodinâmica de líquidos iônicos via simulação computacional.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2006-10-04)
In this work classical molecular dynamics was used to study the
pure ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate,
[BMIM]+[BF4]-, and some solutions based in it. The OPLS-AA force field and
CHelpG derived ...
Influence of desensitizing and anti-erosive toothpastes on dentine permeability: An in vitro study
(2019-01-01)
Objective: This study analyzed the effect of desensitizing and/or anti-erosive toothpastes on dentine permeability. Methods: One-mm dentin discs were prepared from human molars and exposed to EDTA solution (5 min, 17%). ...

Subsites of trypsin active site favor catalysis or substrate binding
(Elsevier B.V., 2002-01-11)
Enzymes enhance chemical reaction rates by lowering the activation energy, the energy barrier of the reaction leading to products. This occurs because enzymes bind the high-energy intermediate of the reaction (the transition ...
Controlled hydrolysis of cheese whey proteins using trypsin and alpha-chymotrypsin
(Humana Press Inc, 2001-03-01)
This study examined the production of protein hydrolysates with controlled composition from cheese whey proteins. Cheese whey was characterized and several hydrolysis experiments were made using whey proteins and purified ...
