Abstract

Biochemistry with a broad and complex scope of material causes students to have difficulty in visualizing or understanding the concepts (metabolic pathways, molecular structures, and terms in biochemistry).This study aims to get an overview of students' learning difficulties in studying biochemistry. The study used a descriptive method. The research subjects were students of Biology Education at one of the universities in West Sumatra. The research instrument consists of a questionnaire of student opinions on learning difficulties and a test of mastery of concepts. It was found that 26.47% of students had difficulties in molecular structure material, 58.82% in metabolic pathway material, and 14.71% in term in biochemistry material. The students have difficulty in learning biochemistry concepts as shown by average lecture achievement score of 0.51 which is in a quite difficult range. The questionnaire results of student opinions on learning biochemistry show that 27% of students like learning using the practicum method.

Abstract

Peptides derived from the phycocyanin pigment of Spirulina plantesis were screened to identify potential natural antibacterial candidates. In silico protein hydrolysis was performed to obtain active peptides, and a multiple molecular docking (MLD) approach was used to to predict the synergistic mechanisms of various peptide combinations with their respective receptors. Nine phycocyanin peptides showed interaction values ranging from -5.1 to -6.0 kcal/mol, compared to the native ligand (BB-78485) with a value of -9.7 kcal/mol. The results demonstrated a synergistic effect, as the binding affinity of peptide combinations exceeded that of individual peptides and the native ligand. Hydrophobic bonds and van der Waals forces played a crucial role in binding to the active site of 2VES proteins. However, ADME studies revealed that two peptides, YCL and ASYF, had poor pharmacokinetic properties. Overall, this study highlights the potential of phycocyanin peptides as antibacterial agents through the application of MLD.
